    Abstract: An electrical wiring device includes a manually adjustable switch, a light emitting diode (LED), a light level sensor, and a microcontroller. The wiring device also optionally includes an occupancy sensor. Light level is sensed through a light pipe and light is emitted by the LED through the same light pipe. When the manually adjustable switch is positioned to energize a load, the LED is deactivated and ambient light level is sensed by light sensors through the light pipe. The ambient light level is compared to a minimum ambient light level to determine if the load will be energized. Alternatively, the LED is deactivated and the ambient light level is sensed through the light pipe when the switch is positioned to de-energize the load. This ambient light level is stored and compared to the minimum ambient light level at a time when the switch is later positioned to energize the load.

  • Patent number: 9756692
    Abstract: Circuits for sensing current levels within an apparatus are disclosed. In specific cases, a constant voltage power supply is used to power an LED lighting apparatus in which there are uncertainties within the forward voltages of the LEDs, which in turn creates uncertainty with respect to the current level flowing through the LEDs. To manage these uncertainties, the current flowing through the LEDs is measured by determining a voltage level across a known resistor and calculating the current level. To prevent the known resistor from causing a significant reduction in the efficiency of the overall light engine, the circuit includes one or more transistors in parallel with the known resistor to reduce the effective resistance in the LED circuit during times that the current is not being sensed.

  • Patent number: 9137867
    Abstract: The disclosed lighting device gradually adjusts from an incandescent bulb color having a 30% dimming rate to a daylight color having a 100% dimming rate. The overall dimming rate is changed to a linear shape, and the ratio of the dimming rates of the incandescent bulb color and the daylight color is adjusted. When changing from the incandescent bulb color to the daylight color, the color is changed to an intermediate color that mixes the incandescent bulb color and the daylight color, and then ultimately is changed to the daylight color, and so it is possible to change the dimming rate without causing discomfort or annoyance in humans, and a comfortable and natural light environment is achieved.
